Moderate unusual earthquake near Lake Kariba, Zambia: Is the man made lake to blame ?

Earthquake overview : Moderate shallow earthquake in a location with very few prior earthquakes. Earthquake-Report.com calls this earthquake moderately damaging as the houses are not prepared to resist earthquakes and as the epicenter location is surrounded by many villages.

22/07-08:17 UTC : Felt reports from the epicenter area. "It was very bad in itezhi tezhi, some buildings have developed cracks.Thanks heavens that no damage was done to humans so that we can VOTE (ER: there are soon elections in Zambia)." "The tremor was at 15:56 hours. Two of my office glass panes cracked."

22/07-08:06 UTC : In local media a fierce discussion is going on to find out why this earthquake happened. Some people blame the Itezhi Tezhi Dam project. Below are 2 people with a diffrent opinion on the origin of this earthquake.
Lemekani Phiri : "The tremor was located in Itezhi-Tezhi district. This is due to the man-made lake there. The weight of the new water body and lubrication of formerly idle faults by the water most likely caused it. And yes, Zambia has the ability to measure (so called Richter scale) and accurately locate the quake. Check with the Geological Survey Zambia. There have been such tremors infrequently since the completion of the lake construction."
"We've always have tremors in Zambia even before the Kariba was made. Its just that they are not as often as those in Asia and South Europe. In Zambia they are like a comet, a rare phenomenon. How do you explain the one that took place in Mocambique and Zim? I think it has something to do with the rift valley. The only advice I can give is for those building houses to put up strong ones. Let's take a leaf from Japan. Thank God no major damages nor serious injuries reported."

Quake-hit: The Greek island of Zakynthos suffered an earthquake of preliminary magnitude 5 - but no one was injured
An earthquake of preliminary magnitude 5 has struck off the Greek island of Zakynthos, but no injuries or damage have been reported, authorities said today.

The Athens Geodynamic Institute said the undersea quake struck at 10.13 a.m. (0713GMT), and had its epicentre about 100 kilometres off the island's south-western coast.

The epicentre was about 350 kilometres west of Athens.

Greece is one of the world's most earthquake-prone countries, and Zakynthos lies in an area of frequent seismic activity. But severe damage and injuries are rare.

Earthquake epicentre.
At least 13 people have been confirmed killed and more than 70 others injured after a strong earthquake struck the southwestern Kyrgyzstan and eastern Uzbekistan border area on early Wednesday morning, officials said.

The 6.2-magnitude earthquake at 1.35 a.m. local time (1935 GMT Tuesday) was centered about 15 kilometres (9.3 miles) east of Okhna, a village in the Batken Province of Kyrgyzstan near the border with Uzbekistan. It struck about 10 kilometres (6.2 miles) deep, making it a shallow earthquake, according to the Kazakhstan National Data Center (KNDC).

The United States Geological Survey (USGS), which measured the strength of the earthquake at 6.1 on the Richter scale, estimated that some 50,000 people may have felt 'very strong' shaking, which could result in moderate to heavy damage. It estimated that some 7.6 million others may have felt moderate to strong shaking.

Quake in Costa Rica Causes River to Disappear

Guacalito River disappears in Costa Rica after Earthquake
Following a series of moderate earthquakes that struck the country Tuesday, residents around the Guacalito River in Costa Rica discovered that the river had disappeared.

Earthquake-report.com reported that sometime after the earthquakes, villagers living near the river, which is located near Armenia de Upala, discovered that the river was dry.

It was not immediately known if the waters of the river had disappeared due to sinkhole activity that can occur after earthquakes or if the earth shaking caused damming that dried up the river near the Miravalles volcano. The quakes were centered near the Nicaragua and Costa Rica border in the same vicinity as the Miravalles volcano.

An entire body of water disappears? Strange but true, and this isn't the first time this odd event has happened.

In 2010, the Iska River in Slovenia disappeared after local residents heard loud crashing and banging overnight. The next morning, the river was dry and the riverbed was full of fish and other creatures. It was believed that the waters of the river had drained through a large crack into an underground riverbed. This disappearance was not believed to have been related to an earthquake.

The quake which had a magnitude of 3.0 was reported at 1:57 a.m.. Sunday about 13 miles west of Waxahachie and 12 miles east, northeast of Cleburne.

An official with the U.S. Geological Survey said Sunday that the quake was at its "most strong" near Venus in Ellis County.

"There might be some cracks in sidewalks and houses may have been shaking a little," said geophysicist Paul Caruso on Sunday. "We don't expect damage from this."

Caruso said that a quake with a magnitude of 5.5 or higher would cause major damages and casualties.

As of Sunday afternoon, the USGS had received 69 reports from residents about the quake in the North Texas area.
